mlx5e_create_ttc_table_groups() frees ft->g on failure of
kvzalloc(), but such failure will be caught by its caller
in mlx5e_create_ttc_table() and ft->g will be freed again
in mlx5e_destroy_flow_table(). The same issue also occurs
in mlx5e_create_ttc_table_groups().

Hi Linus,

Hi Andrew,
I've browsed the code in drivers/net/phy, but haven't found a place
where the SFP module status/change is reported to user-space. Is there a
"standard" way to report insert/remove events for SFP modules, or should
we just add a custom sysfs attribute to our driver?
Thanks,

When mlx5_create_flow_group() fails, ft->g should be
freed just like when kvzalloc() fails. The caller of
mlx5e_create_l2_table_groups() does not catch this
issue on failure, which leads to memleak.

Hello all,
This series fixes race conditions in the xps code, where out of bound
accesses can occur when dev->num_tc is updated, triggering oops. The
root cause is linked to lock issues. An explanation is given in each of
the commit logs.
Reviews in v1 suggested to use the xps_map_mutex to protec
Two race conditions can be triggered in xps, resulting in various oops
and invalid memory accesses:
1. Calling netdev_set_num_tc while netif_set_xps_queue:
- netdev_set_num_tc sets dev->tc_num.
- netif_set_xps_queue uses dev->tc_num as one of the parameters to
compute the size of new_
Accesses to dev->xps_rxqs_map (when using dev->num_tc) should be
protected by the xps_map mutex, to avoid possible race conditions when
dev->num_tc is updated while the map is accessed. Make use of the now
available netif_show_xps_queue helper which does just that.
This also helps to keep xps_cpus
Accesses to dev->xps_cpus_map (when using dev->num_tc) should be
protected by the xps_map mutex, to avoid possible race conditions when
dev->num_tc is updated while the map is accessed. This patch moves the

Dear Reviewer,
When FTGMAC100 driver is used on other NCSI Ethernet controllers, few
controllers have compatible issue. One example is Intel I210 Ethernet
controller on AST2600 BMC, with FTGMAC100 driver, it always trigger
RXDES0_RX_ERR error, cause NCSI initialization failure, removing
FTGMAC100_
When FTGMAC100 driver is used on other NCSI Ethernet controllers, few
controllers have compatible issue, removing FTGMAC100_RXDES0_RX_ERR bit
from RXDES0_ANY_ERROR can fix the issue.

Dear Reviewer,
Use native MAC address is preferred over other choices, thus change the order
of reading MAC address, try to read it from MAC chip first, if it's not
availabe, then try to read it from device tree.

When you say NCSI Ethernet controller here you mean the main system
NIC, right? The MAC on the NCSI side is FTGMAC100, correct?
In that case I'm not sure how user is sup

Currently tests for bpf_get_ns_current_pid_tgid() are outside test_progs.
This change folds test cases into test_progs.
Changes from v9:
- Added test in root namespace.
- Fixed changed tracepoint from sys_enter to sys_usleep.
- Fixed pid, tgid values were inverted.
- Used CLONE(2) for namespa
The Intel I211 Ethernet Controller supports 2 Receive Side Scaling (RSS) queues.
It should not be excluded from having this feature enabled.
